Reviewer: MMmichaelMichael Stawasz from TTorrance, CA United States  
Really great compact light with all the resrve power from a 21700 battery.  I will be buying the new lighted tailcap  (when they are in stock) also the high end belt holster for this light.
P.S. I liked this light so much that I purchased a second........

Reviewer: Jerry Amore from West Chicago, IL United States  
I like this charger because it accepts longer batteries. I have 18650 batteries that have the plastic ring around the positive post. This charger will not charge that style battery directly because the plastic ring around the positive post of the battery prevents the positive poles from touching. I use a small alnico magnet on the positive post and it solves the issue. All other chargers I have will not allow the fit this nitecore charger does. Wish it had a usb output port to charge other items.

5 of 5 super charger July 29, 2021
Reviewer: Mohammed Bait Said from Oman  
I think the market is full of chargers and brands, but high quality and practical specifications are the root of quality. Nightcore is one of the most famous international names in this field.
